1i" this same carrier enter .inlet il? 'llat end irst it will pass through tubes 29, 69, and 46 to the distributor 49 which will eject it through ldie outlet 48 at the station A. Thus, a carrier ot the type shown in Fig. 4 may be dispatched either to station D or station it according to which end is inserted lirst.

rlfhe carrier of Fig. 5 has a flat head 1 and a plugged head 3. li' such a carrier oi'iter inlet 27 plugged end iirstit Will pass through the tubes 29, 69, and 46 and enter the distribut( r 49 which Will eject it through the outlet 47 and cause it to land dat end i'iist in. the distributor 491. rllhis distributor will eject the carrier through the outlet leading 'to the station E. if the carrier oit Fig. 5 enter the inlet 27 flat head first it will be delivered to the distributor 49 lat head first and will topple into the outlet 48 and be ejected at station ii.

The carrier shown in 6 has a recessed head 2 and a plu.v 'ed head 3 so that it it enter inlet 27 recessed head lirst it will be ejected through the outlet 28 and passing through tubes 71 and 460 to distributor 490 will be ected by the latter through the outlet 470 leading` to station l?.

lt the latter carrier were to enter the passage Q7 j'iluggfed end first it Would be delivered plugged end iirst to distributor 49 .vhen it would topple over and be delivered recessed end first to the distributor 491 which would eject it through outlet 480 at the station E.

lllhile l have shown these distributors and the reversing vdevice as separate units it is obvious that one or more of them may be assembled in one housing, but for manufacturing economy and to permit the ready assemblage of the distributors to meet varying requirei'nents as to the number of stations to be served it is preferred to malte the distributors as shown.

By referring particularly to Fig. it

clear that it tv-7o carriers arrive will be through the entrance 2l' With too little interval between them, and it the i'irst carrier be such that it will go straight on through to the outlet 29, the second Carrier, regardless olf its class, Will probably follow the lirst, as the iirst carrier will have opened the gate 5 and may hold it open until the second carrier has entered the outlet 29. Furthermore it the first carrier be o'li a type which topples out through the outlet 28 itinay interfere with and probably will jam the next carrier entering too closely oevhind it. Moreover, it is desirable to keep the outlets of the distributors clear ot carriers, tor if carriers accumulate at `the outlets 'the distributors cannot ituuction. It is thus desirable to provide means 'lior spacing the carriers as they move through the systeni to insure proper operation of the distributing device. j

l have shown a desirable torni ot spacer in Fig. 19, the device there shown being intended to be interposed in the transmission line at a point in advance or' the lirst distributing,` apparatus employed.

As illustrated in Fig. 19, the spacer comprises ahousing 8O having an inlet passage at 79 and an outlet at 81 from which the transmission tube may lead directly to a distributor, as, for example, to the inlet 2?' of the distributor shown in Figs. 7 to 10.

The passage 79 through the housing 8O is preferably circular' in shape substantially to contorni to the shape of the carriers with which it is to be employed. Vlhe casing' 8G is provided at one side with an offset furnishing` a recess 82 adapted to receive the upper end of a carrier when the latter is tilted as indicated in dotted lines in Fig. 19.

Directly opposite to the recess 82 a second recess 87 is provided, this recess being adapted to receive the upper or stop arm ol? a lever`85. This lever is provided With a pair of opposed ears, one on each side, seated depressions 83 in the side Walls ol the housing 87 and pivoted upon pins 84 projecting from the housing. The Weight of thel stop lever is so distributed as to cause it normally to rest with its upper arm against the buffer or cushion 88. A similar buffer 89 is provided in the path of the lower end of the stop lever.

W'hen a carrier enters the passage 79 it drops until it engage-s the lower arm ot the stop lever, such arm normally extending,` in an oblique direction across the passage 79. Engagement of the carrier with this arm turns the stop lever on its pins 84 into the dotted position shown in Fig. 19, causing the upper or stop end of the lever to strike the upper part of the carrier and push the latter over into the recess 82 until it assumes the dotted line position shown in Fig. 19.

The carrier is now tree to drop down through the passage I9 and out through the outlet 81. As the upper end oi: the carrier llO is swung overy out of its normal position it provides a space between its head and the hea-d ot the 'following` carrier into which the stop arm of the lever may enter, thus holding back such following carrier until the iirst carrier clearsthe lower end of the stop lever.n The carriers are thus spaced suiiiciently to permit. a distributor to dis pose ot the first carrier before the following carrier, can land in the distributor.

v'llie stop lever 85,4besides being Weighted automatically to return to its normal posi# top end ot the lerer tends to swingl the lever heel; 'to its nornlsl gos tion thus resistingg the feight 1n peri rising this ogeretlon To permit the stop element ot the lerer to slip freely trein beneath o. carrier its upper 'talee is preferably of ercuute contour struck on en are about the axis oi the pivot pins 81 es e center.

19. Carrier distributing apparatus comprisinga carrier transmission tube having a lateral discharge opening, a one piece gate normally projecting into the tube and pivoted to turn about an axis disposed at the opposite side of the tube from said opening, the axis of the gate lying` in a plane above the horizontal plane of its center of gravity, said gate being movable downwardly and out of the tube under impact ot carriers of a certain from said lateral outlet, the lever when in Voperative position extending into the pasthe lever having a lug projecting* sa toward approaching carriers, said lug being disposed eccentrically with respect to the axis of the passage, and a counteiweight disposed outside oitl the passage adapted normally to maintain the lever in operative position.

21. lin a carrier distributor having a passage therethrough for carriers and a lateral outlet for carriers a lever pivoted to swing about. a substantially horizontal axis disposed at the opposite side oi' the passage from said lateral outlet, the lever when in operative position extending into the passage, the lever having a lug projecting toward approaching carriers, said lug being disposed nearer to that side of the passage having the lateral discharge opening than to the opposite side thereof, and a counterweight exterior to the passage connected to the lever tending to hold that portion of the lever which projects across the passage in operative Carrier engaging position.

22. A carrier sorting device for pneumatic despatch tubes comprising a tube section having an outlet port in one side thereof, a lever pivoted to swing about an axis disposed outside o1 the tube section, said lever having an arm disposed outside of the tube section, a weight rigidly secured to said arm, and a second arm disposed within the tube section, said latter arm having a part adapted to enter the recess of a recessed head carrier passing' along the tube section, said second arm when engaged by a carrier having a non-recessed head swinging downwardly to allow the carrier to pass thereby lifting the weighted arm.

A carrier sorting device lor pneumatic despatch systems comprising a guide tube having an outlet port in one side thereof, and one piece counterweighted lever having an arm normally projecting into the carrier path at a point adjacent to the lowler end of said port, said arm acting' as an abut-ment to retard carriers ot a certain configuration and thereby to cause such retarded carriers to pass out through the outlet port, said abutment swinging to permit other carriers to continue on along the` tube.

24. A carrier sorting` device for pneumatic despatch tubes comprising a tube section having an outlet port at one end and an outlet port in one side thereof, an arm pivoted on said section and extending into the path of travel of carriers passing into the section, said arni being arranged to engage t-he recess in the end of a recessed carrier to interrupt the travel of the carrier and cause the saine to topple through the outlet in the side of said section.

25. A carrier sorting device for pneumatic despatch tubes comprising a top section having an out-let port at one end and an outlet port in one side Wall thereof, a Weighted arm pivoted on said section adjacent to the lower end of said outlet in said side Wall, said arm being arranged to engage the recess in the end of a recessed carrier and thereby causing.)r the carrier to topple outwardly through the adjacent recess in said side vvall While a nonrecessed carrier will swing the arln about its pivot and pass through the outlet port in the end of the section.

In testimony whereof I have affixed my 20 Certicate of Correction.
